Microkernel Devroom 2021 talk recordings
by Martin Decky 14 Jan '21

14 Jan '21

Dear speakers, despite the fact that some instructions from the FOSDEM organizers are still not 100% confirmed as final, I would like to ask you to start your work on the recordings of your talks so that you have at least the first version ready for upload by January 15th. Thank you! I summarize all the relevant information and suggestions that are currently available regarding the recordings below. In case you encounter any issues or would need some help with recording your talk, please do not hesitate to approach me directly. Technical requirements for the video [1]: * Resolution: 1280x720 * Frame rate: 25 fps * Video codec: H.264 video codec, main profile * Video bitrate: <= 2 Mbit/s * Audio codec: AAC audio codec * Audio sample rate: 48 kHz mono * Audio bitrate: 128 kbit/s * Media container: MP4 The upload system will verify that you did indeed follow the above constraints. If you did not, the video will be transcoded first (but this will take longer). Again, please make sure that the length of your recording is strictly shorter than the length of your talk slot. It is strongly suggested that it is also shorter than the length of your talk slot minus 10 minutes (reserved for Q&A). FOSDEM 2021 works on a strict broadcast schedule. The system will ruthlessly cut your talk off at the end of your slot. Content hints: Please do not overload your slides. Make sure everything is readable when scaled down slightly. Upload: You should be able to upload your recording through https://penta.fosdem.org in the upcoming days. In your account, you will find a TODO item. Some tutorials for recording the talks [2]: (1) Using the OBS Studio to record your talk: https://dev.to/erikaheidi/how-to-use-obs-studio-to-record-or-stream-live-pr… (2) Another video tutorial for OBS Studio: https://peertube.xwiki.com/videos/watch/c5cf50e3-2277-440a-b339-34874acd00b3 (3) Using ZOOM to record your talk: https://otl.du.edu/knowledgebase/using-zoom-to-record-a-video-presentation/ (4) Most other videoconferencing tools (e.g. Jitsi) also allow to do a solo call with screen sharing and provide a built-in recording facility. To recap, this is the current schedule of the devroom: Begin | End | Speaker | Title ------+-------+-------------------+-------------------------------------- 10:00 | 10:10 | Martin Decky | Welcome and Introductioon 10:10 | 11:10 | Gernot Heiser | The seL4 Report 11:10 | 11:55 | June Andronick | The seL4 Foundation 11:55 | 13:05 | Renzo Davoli | libioth 13:05 | 13:45 | Norman Feske | Pluggable Device Drivers for Genode 13:45 | 14:25 | Anastassios Nanos | Hardware Acceleration for Unikernels 14:25 | 15:05 | Simon Kuenzer | Is the Time Ripe for Unikernels ... 15:05 | 16:05 | Martin Decky | State of Microkernels in 2021 [1] https://github.com/FOSDEM/video/wiki/FOSDEM-2021-video-email-to-speakers [2] https://github.com/blackbeard334/fosdem21-emulator-devroom-cfp/blob/main/SP… Best regards Martin Decky

Microkernel Devroom 2021 working schedule
by Martin Decky 02 Jan '21

02 Jan '21

Dear all, please see below the current working schedule of the Microkernel Devroom at FOSDEM 2021 (this email also serves as the official confirmation of the acceptance of your talk, in case you did not check Pentabarf yourself already). Begin | End | Speaker | Title ------+-------+-------------------+-------------------------------------- 10:00 | 10:10 | Martin Decky | Welcome and Introductioon 10:10 | 11:10 | Gernot Heiser | The seL4 Report 11:10 | 11:55 | Gernot Heiser | The seL4 Foundation 11:55 | 13:05 | Renzo Davoli | libioth 13:05 | 13:45 | Norman Feske | Pluggable Device Drivers for Genode 13:45 | 14:25 | Anastassios Nanos | Hardware Acceleration for Unikernels 14:25 | 15:05 | Simon Kuenzer | Is the Time Ripe for Unikernels ... 15:05 | 16:05 | Martin Decky | State of Microkernels in 2021 If you see any issue or a scheduling conflict on your side, please do not hesitate to approach me. I am certainly also open to any other comments and suggestions. I will consider the schedule confirmed and fixed by the end of Sunday, January 10th 2021. A few remarks: (1) The time values in the schedule are in UTC+1 and _include_ a Q&A part of 10 minutes for each talk. The semantics of the "Duration" entry in Pentabarf has been changed by the FOSDEM organizers to reflect this as well (while the length of the pre-recorded presentation itself has a dedicated entry now and it will be ultimately derived from the exact length of the video recording). The latest info about the organization of the devroom from the FOSDEM organizers could be summarized as follows: The pre-recorded videos will automatically start streaming at the given time according to the schedule and after each talk finishes streaming, the live stream for the Q&A will start. Further discussions could be performed in parallel with the talk (and other talks) via Matrix/IRC and in a dedicated "hallway" stream for each devroom. (2) The initial instructions for the pre-recording of the talks can be found at [1]. Similarly to the organization of the devroom itself, this still appears to be a work-in-progress and therefore I suggest waiting couple more days before you start doing any recording. I will let you know and update the CfP page for your reference when the discussions among the FOSDEM organizers appear to settle. (3) However, be ready to match the length of your presentation to the original duration you have proposed. If your recording is longer (but still within the constraints of the schedule), you will cut in into your Q&A. If your recording is longer than the slot in the schedule, the system might reject it completely. Having written than, we can certainly afford to be a bit cavalier with the length of the talks this year (due to the small number of submissions). Thus, if you feel you would make good use of a longer slot, please let me know. (4) The last item on the schedule is intended as a live panel discussion (which I will humbly moderate). If you would like to participate in the panel or suggest somebody who should participate, I would very much appreciate that. I will also approach some key people in our community directly.
